BALING- Panes.

Application filed June 15,

To all whom it may concern Be it known that 1, Di; Yon C. CHIPMAN, at citizen of the United States, and residing at Ann Arbor, in the county of lh ashtenaw and State of h lichigan. have invented a new and. Improved Baling. Press, of which the following is a specification;

This invention relates to means for com pressing. hay, straw and similar materials into bale /and its object isto provide a machine of this character in which the division blocks which limit the length of the bales are automatically positioned, and to provide a machine with a feeding mechanismfor the material to be baled, whose operation isinterrupted' during); the timethe division block is moved to itsproper position.

A further object of this. invention is to provide a baling press with a carrier which will receive the material to be baled at a distance from the press and deliver it into thepress, thereby eliminating the dust and floating chaft which is so often found objectionable to the workmen at the machine.

A. further object of this invention is to provide means for automatically placing the division blockat the front end of the balinp; chamber so that it may compact all the material in the chamber when moved back.

ln the accompanying drawings, Fig. 1 is a side elevation of this improved baling; press with the material carrier removed. Fig. 2 is a perspective of a division block. Fig; 3 is a front elevation of the machine. l in'. 4i is a section on the line 4l-4: of 3. Fig. 5 is a plan of the actuating mechanism of the device for positioning; the division blocks and the feed checking mechanism on a "laip 'er scale. Fig.6 is a front clevationof the forks forinterrupting the feed. Fig. 7 is an elevation of a cam at the outer end of the actuating; mechanism for the division blocks. 8 is an elevation of the upper end offithe tripping; arm. Fig. 9 is aplan of the. machine. s V s Similar reference characters refer to like parts throughout the several views.

his is usual in machines of this cha acter 50 the framework consists of four horizontal angle bars 1 connected together-by means of the upright barsfZ and cross bars 3. lhe rear end of this machine is constructed to permit the longitudinal bars 1 to separate vertically to permit easy removal of the bales when formed and bound, t-his'beingrebars 42.

sisted to some extent by means ofthe rods l and the springs 5 thereon. Other machines on the market permit these bars 1 to separate sidewise forthe same reason.

The springs 5'control the friction between the side bars and the division blocks and the completed bales and thereby control the degree of compressionof the straw or other material being handled by the machine. In Fig. 1 the frame of the machine is shown resting on cross sills 6 and supported by wheels 7 which are shown conventionally as nonovelty resides therein.

The straw or other material being. baled is compressed by means of a plungerlO which moved longitudinally back and forth within the frame bars 1 by a connecting rod 11 which attaches. to a crank; pin 12 extending between two large gears 13 havingtrunnions or stub shafts 1e mounted in bearings carried by the frames 15 which connect the. upper and lower side bars 1 of the frame in pairs. Mounted on the upper side bars are the pedestals 16 which carry the shaft. 17 on which is mounted the pinion 18 which meshes with one of the gears 13, and thepulley 19 or other driving mechanism by which power is transmitted to the machine. On the shaft 14 is a pinion 20 which meshes with a gear 22 having; a cam slot in one side to receive a pin 241 in the forward end of a lever 25 which will be hereafter described. Any well known antifriction device may be used to reduce the friction: of the pin 24; within the groove Extending from the upper side bar 1 on the left hand side of the machine when looked at fromthe right in Fig. 1,. and as shown in Fig, 3, is a: table??? whose outer edge maybe supported by legs 28. On this table are mounted pedestals 529 which sup port a shaft to which is attached a pulley 31, (seeFipg. On the outer end of the main shaft 17 is pulley 38 which connects to the pulley 31 by means of a belt 3 1. This belt passes around the idler pulleys 35which are supported in any desired manner. Any other desired means may be employed for driving); the head shaftBO from the main shaft 17. a a

' A tail shaft 40 is'carried in bearing supported by the legs ll. and the upper end of the legs ll are properly spaced from the pedestals 29 by means of the longitudinal Proper-rollers 4:3 are secured to these shafts'30 anddO andzaround them pass the conveyer belts 44 to which are secured the cross slats 15 which carry the straw, hay or other material to be baled from a hopper 46. These belts slide on a plate 47 of any desired material which constitutes the bot tom of the hopper and also prevents the ma terial to be baled from getting lost. The longitudinal bars 42 serve as the sides of the trough of which the plate 47 is the bottom.

This carrier can be made of any desired length extending from a threshing machine to the baling press and thus avoiding the dust and chaff which usually envelopes the workmen and the baling press when the straw is delivered directly from the threshing machine to the baling press.

Small brackets 50 are mounted on the inner ends of the longitudinal bars 42 and carry a shaft 51 to which the curved arms 52 are attached. These arms are adapted to swing down from the position shown in Fig. 3 until their outer ends substantially contact with the apron 53 extending from just below the shaft 30 to the upper angle bar down which board slides the material being baled into the machine. lVhen these fingers are in their lower position, the material passing to the machine is temporarily stopped.

On the front end of the shaft 51 is an arm 54 to which the link 55 connects and this link has an eye 56 slidable on the rod 57 whose ends are attached to the side bars 1 as shown in Fig. 1. As stated before, the gear 22 has a cam slot 28 to receive the pin 24 in the lever 25, which arm is pivoted at 58 on the small bracket 59. This lever swings constantly on this pivot which is also the pivot of a second lever 60 which is normally at rest.

The bales A of straw or hay are moved step by step to the rear end of the machine by the plunger 10, the dividing blocks 61 being inserted at intervals as hereafter described. After a dividing block has been inserted, the attendant places wires 62 around the bale A, being enabled to do so by reason of the grooves 63 in the faces of these blocks. He places the lowermost wire around the trigger 64; so that when the block 61 reaches the position shown in Fig. 1, the next stroke of the plunger 10 will move this block and the trigger 64C rearwardly sufticiently to not only trip this trigger but also disengage it from the lower wire 62 so that the spring 65 can return the trigger.

Mounted on the pin 66 is a control arm 67 having a beveled upper end (Fig. 8) which is normally in the position shown in Fig. 1 and in dotted lines in Fig. 5. A link 68 connects this control arm to the trigger 64. The lever 60 has a lug 69 that rests on the eye 56 and holds up the arms 52 and pivoted on the end. of this lever is a latch 70 adapted to swing from the dotted line position shown in Fig. 5 to the solid line position under pressure of the spring 72 when the control arm 67 has been moved out of its normal position. On the rear end of the lever 25 is a dog 73 (Fig. 7) which has a beveled outer edge so that if the latch 70 happens to be swung inward before the rear end of the lever 25 comes down, this dog will push the latch out of its way.

lVhen the control arm is swung back to release the latch 70, the lever 60 waits to be lifted by the lever 25 and when this occurs, the lug 69 permits the arms 52 to drop into the path of the material passing into the machine. At the same time, the lever 60 causes the next dividing block to swing into position over the receiving chamber.

A bracket 102 on the upper bar 1 has a pivot 103 for a lever '71: to which the link 75 connects, its opposite end. connecting to the end of an arm 76 nrojecting from the lever 60. To this lever is attached the block carrier consisting of channel shaped sides 77 connected by two cross bars 78. The division block is slid into this carrier by the attendant and is held in position by springs 7 9 shown in dotted lines in Fig. 3. When the arm 76 on the lever 60 is elevated, the carrier swings to the right and positions the dividing block directly over the receiving chamber of the machine. It will be noticed that the gear 22 is twice the size of the pinion 20 so that the movements of the block carrier is comparatively slow.

Referring now to Figs. 1 and 3, two supports 78 are shown carrying cross pins 79 and 80. These supports may be stiffened by the braces 81. A double stamping lever 82 is mounted on the pivot 79 and its lower end connects to the frame 88 on the connect ing rod 11 by means of the link 84. A stamper 85 is hung from the outer end of the lever 82 and is kept vertical by the link 86 extending from the pin on the supports 78 tothe pin 87 on the stamper. This stan'lper drops into the baling chamber just before the plunger 10 reaches the forward end of its stroke and presses the straw or hay being baled down into the baling chamber.

. l lxtcnding across between] the ln'aces 8] is a pivot 9 on which a striker,;.le'\'er 9] is mounted. The lever carries a pivot 92 from which the connecting rod extends to the pivot 94: on the striker 91. This striker moves faster and in advance of the main stai'nping lever and when the dividingplate has been positioned as above describech it presses it down into the baling chamber just as the plunger 10 has moved forward of the position of the dividing block.

It will be noticed that during the time the block carrier is above the balling chamber, the arms 52 are holding back the hay or straw and that therefore there is nothing to prevent the dividing block being properly positioned. As the movement of this device has one half the speed of the plunger 10, the dividing block Will be forced to the rear end of the baling chamber and the plunger will have begun its forward movement before this hay or straw is released by the arms 52.

I claim 1. In a baling machine ofthe character described wherein the material to be baled is compacted Within a baling chamber between dividing blocks, the combination of a conveyer to carry the material to the baling chamber, means to interrupt the passage of the material, means to position dividing blocks in the baling chamber, and means connecting said positioning means for the dividing blocks and the interrupting means to cause the latter to act While a dividing block is being positioned.

2. In a baling machine of the character described wherein the material to be baled is compressed Within a baling chamber bea tween dividing blocks, the combination of a conveyer to carry the material to be baled to the baling chamber and an inclined apron extending from the discharge end of the conveyer to the baling chamber, a device to stop the passage of said material at said apron, means to position dividing blocks in the baling chamber, and a connection operated by said last named means to move the material-stopping device to operative posi' tion on the apron to restrain the discharge of material into the b'aling chamber While a dividing block is being positioned.

3. In a baling machine of the character described wherein the material to be baled is compressed Within a baling chamber between dividing blocks, the combination of a conveyer to carry the material to be baled to the baling chamber and an inclined apron extending from the discharge end of the conveyer to the baling chamber, a device to stopthe passage of said material at said apron, means to position dividing blocks in the baling chamber, a connection operated by said last named means to move the material-stopping device to operative position on the apron to restrain the discharge of material into the baling chamber While a dividing block is being positioned, and means controlled by the movement of the bales from the baling chamber to time the operations of the positioning device for the dividing blocks and of the device to stop the passage of said material to the baling chamber.
